Understand and optimize your electrical systems with our Total Harmonic Distortion (THD) Calculator. Accurately measure THD for voltage or current based on fundamental and harmonic components, ensuring superior power quality and signal integrity. Ideal for engineers, technicians, and anyone concerned with signal fidelity in power electronics and audio systems.
Formula:
The formula for Total Harmonic Distortion (THD) is given by:
THD = (√(H₂² + H₃² + ... + HȈN;²)) / H₁ × 100%
Where:
- H₁: RMS amplitude of the fundamental frequency component.
- H₂, H₃, ..., HȈN;: RMS amplitudes of the 2nd, 3rd, ..., nth harmonic components.
